Drill bit Proline 92530, metal, Ø25 mm, length 300 mm, 1 pc

Proline 92530 metal drill bit, Ø25 mm and 300 mm length, supplied as a single piece. This twist-type drill bit is designed for drilling metal and similar hard materials where a precise 25 mm hole is required. The bit is intended for workshop, construction and maintenance tasks and fits drills that accept 300 mm length bits of this diameter.

Advantages

The drill bit features a specially shaped solid carbide insert that enhances durability and cutting performance, supporting accurate centered drilling and reduced load on the tool. Double twist flutes promote faster chip evacuation to help maintain stable drilling progress and reduce heat build-up. Supplied as one piece, the bit provides a consistent diameter and length for repeatable results.

Suitable for (tasks / use cases)

• Drilling 25 mm holes in metal sheets, plates and profiles
• Workshop and maintenance drilling where a precise larger diameter is needed
• Construction tasks involving metal fixings or through-holes

Key specifications

• Material compatibility: metal and similar hard materials
• Cutting head: solid carbide insert for improved wear resistance
• Diameter: 25 mm
• Overall length: 300 mm
• Flute type: double twist for efficient chip removal
• Supply: 1 piece

How to use

Secure the Proline 92530 bit in a compatible drill or drill press with an appropriate chuck capacity. Mark and center the drilling location, use a center punch if required to prevent walking. Start at low speed to establish the hole, then apply steady pressure and increase speed as appropriate for the metal being drilled, with coolant or cutting fluid where recommended. Withdraw occasionally to clear chips and avoid overheating; maintain a straight drilling axis for an accurate 25 mm hole.

Usage recommendations

Use cutting fluid when drilling thicker or harder metals to extend tool life and improve finish. Do not exceed the recommended speed and feed for the material; monitor bit temperature and clear chips frequently to prevent clogging and reduce wear.
